In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

The -011 versions incorporate a rotor modulation modification on the VOR instrumentation circuit card This modification includes an RC filter at the outputs of the sine/cosine DC signals that smooths these outputs to minimize the effects of interference by rotor action of a helicopter.
No, although the -01X versions incorporate a rotor modulation filter on the VOR instrumentation card for helicopter applications, the pin designation for the 27.5 DC Bus is different for the two versions. On the -01X versions, the 27.5 DC is assigned to Pin P1-41. On the -00X versions, the 27.5 DC is assigned to Pin P1-18.
